Huawei still employs 1,400 people in the US but its R&D department has decreased by 300 people, and the sales team has also seen a notable decline in size.

The company has now revised its long-term plan for enterprise business, and William Xu, chief executive of the unit at Huawei, said that its target of $15 billion in revenue by 2017 was “too optimistic”.

While it is now aiming for $10 billion by 2017, Xu still expects revenues to grow by 45% this year, against the 25% growth of the same division in 2012.
